Does the 9th Circuit have jurisdiction to hear a claim that a federal district court abused its discretion by sentencing a convicted criminal to a reduced sentence based on his criminal conviction?

^2. See United States v. Pedroza, 355 F.3d 1189, 1190-91 (9th Cir. 2004) (per curiam) (no jurisdiction under 18 U.S.C. 3742 to review defendant's claim that district court "abused its discretion by failing to reduce his offense level, and consequently his sentence, to a degree that he believes properly reflects the assistance he provided to the government"); United States v. Doe, 351 F.3d 929, 932 (9th Cir. 2003) (same); United States v. Arishi, 54 F.3d 596, 597-98 (9th Cir. 1995) (same).
